Abstract
In many fields of engineering and exploration geophysics knowledge of the near surface structure is of special interest; eg . in the investigation of waste disposals, the exploration of the underground for rail road tracks, the recultivation of former industrial areas or in the search of foundations for archaeological purposes. Even if the actual target in oil and gas exploration is burried deep in the Earth, the near surface structure is needed to be known in order to apply residual static corrections to improve the signals from deep reflectors. Our scope is to show by a numerical model study that near surface inhomogeneities can be localized by group travel time tomography of Rayleigh and Love waves of different frequenties.
